I haven't found any way to do either in the macro language.

You can do this in JavaScript by using a DialogListener. Here is an example:
listener = new DialogListener() {
dialogItemChanged : function(gd, event) {
state = gd.getNextBoolean();
checkbox2.setState(state);
return true;
}
};
gd = new GenericDialog("DialogListener Demo");
gd.addCheckbox("Checkbox 1", false);
gd.addCheckbox("Checkbox 2", false);
checkbox2 = gd.getCheckboxes().get(1);
gd.addDialogListener(listener);
gd.showDialog();
